Other modules / Zentyal 5 VPN configuration
« on: September 20, 2018, 12:28:33 pm »
Hi all, I'm having trouble configuring a VPN on a network having three Zentyal 5.1 servers used as a Gateway, Domain Controller and Mail Server respectively.
The network configuration is as follows:

Internet --- [eth0]Gateway Server[eth1]---[eth0]Domain Server[eth1]---Switch---[eth0]Mail Server
                                                                                                          |
                                                                                                          --------Local Network

The goal is to create a VPN on the Domain Server but when I try to connect it with OpenVPN I have the following error:

Thu Sep 20 11:57:32 2018 MANAGEMENT: >STATE:1537437452,RECONNECTING,tls-error,,

These are the servers configurations:
Gateway:
 --eth0 external
 --eth1 internal ip: 192.168.20.1

Domain:
--eth0 external ip: 192.168.20.254
--eth1 internal ip: 192.168.10.1
--DNS Forwarders: 192.168.20.1
--Domain: mydomain.local


Here is what I did:

  • Created a certificate for clients named VPN-Client
  • Created a VPN server named VPN-Server, configured as follows:
     Server Port: UDP 1194
     VPN Address 192.168.30.0
     Server Certificate: certificate autogenerated by Zentyal
     Client Authorization: VPN-Client
     Tun Interface, Network Address Translation, Redirect Gateway enabled
     Advertised network:
     --Network generated by Zentyal: openVPN-eth1 ...
     --Internal network called "internal"
  • Enabled the UDP service on port 1194 both ingoing and outgoing in the firewall
  • Generated the Bundle client with the following parameters:
    Client's type: Windows
    Client's certificate: VPN-Client
    Server Address: my_public_address

Advices? What did i do wrong?

Regards,
Riccardo.

Hi,

I have a zentyal 5.1 installation and I am trying to connect a QNAP server to the LDAP.
Below LDAP information:

DN base
DC=xxx,DC=local
Default Users DN
CN=Users,DC=xxx,DC=local
Default Groups DN
CN=Users,DC=xxx,DC=local

I've tried to connect with Administrator account, with another account part of domain group and even with ebox but i always get the error: "you are not allowed to use this function".

Previously the QNAP was connected to a Zentyal 2.2 server which, in LDAP settings, gave to me user and password i had to use for the connection, but in Zentyal 5.1 this informations are not shown.

How can i find right user and password?

Regards.

Other modules / HTTP Proxy problem Zentyal 5.1
« on: May 21, 2018, 12:48:31 pm »
Hi,

I have installed zentyal 5.1 in a server connected to two router and a lan, but with explicit proxy i can't access the web
Below what i've done:

1 - Set eth0 (connected to the first router) as external with IP 10.10.11.254
2 - Add a gateway with IP 10.10.11.1 (first router IP)
3 - Set eth2 (connected to the lan) as internal with IP 192.168.2.1
4 - Set proxy's rules
5 - Set proxy in a local pc (i set 192.168.2.1 as address and 3128 as port)

Everything seem to work fine, i can access the internet and the proxy blocks the sites i set.

Then i tried to connect the second router to the server:

1 - Set eth1 as external with IP 10.10.10.254
2 - Add a gateway with IP 10.10.10.1 (second router IP)

But when i try to navigate the proxy blocks every sites, even google.
I also tried to connect only the second router but no changes, so i assume, the problem is in the second connection settings.

Any advice?
